Scientists have named a new type of memory loss, called "Primary Age-Related Tauopathy" (PART).

PART is often misdiagnosed as Alzheimer's disease, but it has distinct characteristics.

PART is characterized by the buildup of tau protein in the brain, leading to memory loss and cognitive decline.

Unlike Alzheimer's, PART does not involve the buildup of amyloid plaques in the brain.

PART typically affects people over 80 years old, with a higher prevalence in those over 90.

PART leads to memory loss, difficulty with word-finding, and other cognitive decline symptoms.

PART has distinct brain patterns, including tau protein buildup in the hippocampus and cortex.

Researchers have established new diagnostic criteria to distinguish PART from Alzheimer's and other dementias.

Accurate diagnosis of PART may lead to different treatment approaches, as Alzheimer's medications may not be effective.

More research is needed to understand PART's causes, progression, and optimal treatments.
